Dr Bonnie made a great point.  Our written prescriptions have the DEA number clearly printed on them, apparently a requirement in Virginia statutes.  Any public posting of the complete DEA number opens the door for fraudulent activity and abuse of controlled substances as well as the "system."  We should be seeking revision of the pharmaceutical regulations as well as the requirement for posting the DEA certificate.  We have seen the change in credit card receipts to only display the last four numbers.  Why wouldn't this serve a similar purpose with the DEA number?
